In-Mold Labelling (IML) Electrostatic
Static charges can be used to pin a decorative label tight against the inner mould surface during injection moulding without the use of vacuum. This procedure greatly improves finished product quality. Outside the mould a robot presents the label to a charging bar which applies an electrostatic charge to the label. The label is then placed into the mould cavity, where it sticks due to the electrostatic bond between the label and the metal mould wall. The label will not slip or change position in the mould.
Device used: HDC Charging Bar
